Decisons decisions to mod or to buy

[ikold]

I've got an 08 Rev XP 163 that I got new. It is pretty much stock (except for a can) and it needs a little more juice. Took it to Felker's and was going to have them go hog wild on it. Only problem is that "hog wild" cost about 4k.

Figure I could sell the sled for about 6 and change.

So the question for the group is, am I better off selling the sled stock and looking in the swapmeet for a turboed Polaris dragon or M8. Or doing all the mods to the XP.

The felkers mods don't really do anything with the engine for additional power though I'm told what they do has a big effect.

Need to make a decision fast as I think Haydays would be a great place to find a new sled!

You can do a 860 on the XP for less than $2K, go with a 174-16-2.5 for another $1K. That and proper clutching and it will be right there with any pump gas turbo with less headaches and less weight. have been down both roads and for ME, the XP is the right sled.
I'm curious what they do for $4K that doesn't add power?? That's alot of $$!

I'm not seeing how an 860 pulling a longer track will stay with the turbo's. I think it depends on the type of riding you do. If it its going to be 4 g's do the turbo. If you are trying to save cash then stay with the xp.

You have to see it to believe it STOCK XP with 174 will hang with PG turbo's of 154-163 length on DEEP climbs. At least that's what I witnessed on many occasions last year. Now turn up the boost over 10#'s and it's another story.

 

[ikold]

I'm told the 860 BB kits do not add much more power?

 

[winter brew]

An honest 20HP with proper porting, jetting, timing, exhaust.....some claim more but I'm not big on HP numbers.

Depending on what elevation ,type of riding and how reliable you want your sled should be the deciding factor. Personal preference is key to your decision.

Ya I think you should sell it and get an M8 way better choice. On the swap meet you can get a 2007 M8 turboed for like 8 thousand.

Seeing that 4K is nothing to sneeze at; what exactly are they proposing?

Priorities might be:
- clutching
- port/polish
- domed heads
- revalve suspension
- etc..etc...

Not sure of exact costs, but that should put you under 4k and be quite competitive.

If you do a PG Dragon Turbo, is there a shop in the area that can help maintain it?

Best of luck!

BIG BORE 860(155+20) @7,000'=140hp approximately. TM8(200hp) @ 7,000'=200hp approximately. I think that's about all there is to say about that. 800R, in my opinion is suspect when it comes to reliability so if I was making the choice I'd do the Cat pg800. Once you clutch a boosted sled your done with clutching regardless of where your riding. If you want to see what these sleds are capable of with a good rider check out what Chris Burant does with them. I doubt there are many out there that can hang with that guy but the sleds are pretty straight forward. The RTR800 that is!

wowee!
Same as every other thread where turbos are mentioned. Start talking aobut them & all that spews from a keyboard is bullsh*t.
the big bore loses 35 hp in 7k feet (that part is true), but the turbo loses absolutely nothing in 7k

Are there that many people that just have never run with good running sleds to understand the difference? I see Decently modded M1000's spank PG turbos easily, but if you go by the above math this couldn't be possible, no way.
(btw, I own one & LOVE it, but am capable of understanding the difference between liking something & thinking it destroys all others & loses no HP with altitude) I would go with a t-m8 myself if you want a great machine, you'd love it.


Aside from the turbo stuff,

Keep in mind that when you get the new sled you'll still have a stock sled, so if you want to get a few extra HP, you'll still have to spend money on that sled, so now you're in the hole even more.

"The felkers mods don't really do anything with the engine for additional power though I'm told what they do has a big effect."

I think you must have a bit of a misunderstanding with felkers, I can't imagine what they would do for 4k that would not add power. They do a little less port work than some, but it seems to work well. They're good shop to get 95% of what that motor is capable of & that's as much as most folks need/want.

IF you were talking about a 5 year old sled I'd say get a new one, but with an 08, if you have one that runs well, and you like the chassis then spend a few bucks to make it run the way you want!

Also, if Felkers is your local dealer, that should be a big factor, the other brands are more difficult to support down there now which makes for more driving when you want to get it worked on.

Apparently I touched a nerve but I also forgot to mention that I've had an 840bb. It cost me $2500 cd and a piston in the first 100mi. It was not what it was cracked up to be and even though the engine was jetted for the alt. it was obviously on the edge.
Turbos don't "Destroy All Others" and there was no mention of that, and the loss of hp vs non t sled of any kind is not in favor of the n/a sled. The question asked in this thread was , Buy a tDragon or tm8 or work up an XP. My vote is for the TM8.

 

[Yamahamod]

4K sounds like alot $ for not touching the motor. 1,500 bucks in labor probley

Stick with the xp and have it set up right and do a mod or two to it. Wait till the Denver snow show comes around and go talk to a few diffrent people on what would work best for you since you are apperently looking for information on what works and what dosent. My .2

By the way, Don't put a 174 under it.

My vote is for a TM8 as well, look at my sig!! My only issue is with people that listen to the BS math when it comes to turbos. I'm tired of hearing people that REALLY BELIEVE that a turbo loses no power at elevation.

Hop in your diesel, go to 5k, then come up to 10k, your turbo loses no power???

On a sled, yes you can turn up the boost, but it still is not possible to regain ALL of that power, it does not & will not happen without other changes.

Just think of this, if a turbo was 200 hp at 10,000 feet, it would theoretically take a 300 hp NA sled to beat it. Why do I see them being beat with 220 or so HP sleds?

I'm not arguing the fact that turbos are great, I love ours, I am arguing the math that gets twisted with hyperbole & straight up non truth.

Do the math. Its simple. Check out Frenchie on an 800 summit('06 I believe) pulling Monster Shute at Revy. Its not all about the sled

Yea why would you want a 174. Unless you don't like getting stuck as much, don't like breaking trail in bottomless pow in steep tight trees and oh yea climbing.

So, JK - what did you end up doing?

Did you get a straight program out of Felker, or go with a new buggy?

Snowing up here!!
